1999 Isuzu Rodeo Left Turn Signal freezes on when hitting brake - Uhaul trailer kit installed.
I have a 1999 Isuzu Rodeo, bought it 3 years ago with a U-haul hitch and harness installed. Have noticed headlights and dash lights dimming then brightening when I come to a stop light. Do not see it so much driving. Autozone tested it and said bad battery - changed battery this cycling of light intensity greatly diminished. Autozone says alternator is fine. Yesterday right before getting battery - left turn signal works until I hit brake, then it freezes on. Let off brake and it works. I took apart light assembly -- pins look clean no scoring or melting. no wires seem frayed or shorted (including u-haul). Any ideas what this is?
could be a bad grond on your trialer light hook up so it is back feeding on you. Make sure you check and clean the ground wires
